AVS+
This feature is specific to AviSynthPlus. It is not supported in other AviSynth versions.

Extract a plane from the source clip.
Resulting clip is Y-only (Y8, Y10 etc. as appropriate)
Replaces ShowAlpha/Red/Green/Blue, UToY/VToY and ConvertToY8 with high bit depth support.

Syntax and Parameters

ExtractY(clip)
ExtractU(clip)
ExtractV(clip)
ExtractA(clip)
ExtractR(clip)
ExtractG(clip)
ExtractB(clip)

PlaneToY(clip, string plane)

clip   =

Source clip.

If specified plane does not exist, an error is raised.

string  plane = "Y"

The color plane to be extracted.

If specified plane does not exist, an error is raised.

ShowY(clip, string pixel_type)
ShowU(clip, string pixel_type)
ShowV(clip, string pixel_type)

clip   =

Source clip. Accepts 8-16 integer bit depths, but not Float.

If specified plane does not exist, an error is raised.

string  pixel_type = (same as clip)

Set color format of the returned clip.

Cannot convert bit depths or YUV↔RGB, but can convert from 4:4:4 to 4:2:0 etc.
